It would make perfect sense since it could take place in the year between the manga and 3 or just before the manga. And since we have confirmation that Nero is Vergil's som this makes it more likely to be the case. Besides, over a decade can mean up to 19 years, which still puts Vergil's Fortuna trip at just about the same period.
